Aquaphilia is a sexual fetish involving an extreme love of water. The term literally means "water lover." Aquaphilia includes a sexual interest or arousal created by watching others in water, holding their breath underwater, and sexual activity in water or underwater.
Aquaphilia is considered a paraphilia because this sexual fetish can have a negative impact on the life of the aquaphile. Like those who enjoy autoasphyxiation, aquaphilies are commonly aroused by the element of holding their breath. In this fetish, it is done underwater. This can be dangerous both in partner play and solo masturbation.
